ABSTRACT

A delta 1-tetrahydrocannabinol (delta 1-THC) metabolite has been identified as an O-glucuronide of delta 1-THC in the human urine after oral administration of delta 1-THC. The metabolite was present in small amounts and its identity was confirmed by comparison of its mass spectrum to that of a reference compound.
